7 Claims.

This invention relates to outside weatherproof-lng coverings for thewalls and other exposed surfaces of building structures. Moreparticularly, it relates to coverings comprising a comparatively rigidfibrous base provided at its outer side with an asphalt impregnated feltcovering lhaving its weather side covered by dierently colored particlesof granular material arranged to simulate a vdefinite ornamental patternsuch as a brick, stone or tile surface. Examples of such coveringmaterials are disclosed in my co-pending applications Serial Nos.584,109, 584,110 and 584,111 filed Dec. 31, 1931.

The principal object of the present invention is to improve theconstruction and weather-proofing characteristics of the horizontaljoints provided between adjacent sections of the covering material whenthe latter is applied to cover a wall or other exposed surface.

Another object is to improve the insulating and -fireprooling qualitiesof the comparatively rigid base to which the ornamented felt coveringportions of the covering are applied.

Other objects, advantages and characteristic features of the inventionwill be more readily understood from the follovnng detailed descriptionand accompanying drawing, in which,

Fig. 1 is a fragmentary perspective view showing several sections of thecovering material constructed and assembled in accordance with thisinvention.

Fig. 2 is a vertical sectional view through two assembled sections ofthe covering material illustrating a slight modification as comparedwith the construction shown in Fig. 1.

Fig. 3 is a view similar to Fig. 2 but showing a further modification.

Fig. 4. is a view similar to Fig. 2 showing a still furthermodification.

In Fig. l, I have shown three sections of the covering material appliedto cover a vertical wall surface 5, said sections being designated A, Band C. Each section comprises a comparatively rigid fibrous base 6 whichmay be produced in accordance with the practice usually followed in themanufacture of insulating boards composed of cellulose or other fibrousmaterials. In each instance the weather side of the base is covered by afelt sheet 'l which, as more fully explained in my previously mentionedapplications, is impregnated with a tarry or bituminous compound.

and has its outer surface covered by diierently colored particles ofgranular material arranged thereon according to a definite patternsimulating the appearance of a brick, stone, tile or other surface. -Inthe present instance the granular particles are arranged to presentbrick colored areas l separated by intervening mortar colored areas 8.

The present invention, as embodied in the con- 5 struction illustratedin Fig. 1, resides in constructing the upper and lower edges of thesectionsA, B and C to improve the wcatherproong characteristics of thehorizontal joints provided at these edges. As herein shown a recess 9 ism provided in the outer surface of each base 6 immediately adjacent itsupper edge. This recess may be produced by a molding or pressingoperation during manufacture of the base but is preferably produced bycutting away a portion of 15 the outer surface after the base is formedand cut to the desired length and width. The depth of the recess 9 isapproximately equal to the thickness of the felt covering sheet l, theupper edge portion of which is depressed into contact 20 with the wallsof the recess as indicated at '7a. Directly opposite the recess 9 theinner surface of each base 6 is shaped or cut away to provide a similarbut deeper recess Ill. In effect, these opposed recesses 9 and l0provide, at the upper 25 edge of the base, a tongue Il having its outersurface completely protected by the overlying depressed portion 1a ofthe associated felt covering.

Immediately adjacent its lower edge the outer surface of each baseis-shaped or cut to provide 30 a tongue portion I2 projecting below themain body of the base to form the inner Wall of a tongue receivinggroove I3, the outer Wall of which. is formed by the opposing lower edgeportion 'lb of the associated felt sheet 1. 35

With the sections assembled as shown in Fig. 1 it will be noted that thetongue Il at the upper edge of each section is fitted in the groove I3formed in the lower edge of the next upper section so that the feltcovering portion 1a of the tongue 40 is in contact with the lower edgeportion 'lb of the felt covering forming the outer side wall of thegroove.

When fastening the sections of the covering material to the wall 5,certain of the fastening nails are driven through the overlapping feltportions 'la and 1b and through the underlying tongues l l and I2 of thebase members 6. The felt portions 1b are thus pressed firmly against theunderlying felt portion la to provide a waterproof horizontal jointbetween the sections and this waterproofing 'characteristic of the jointis further improved by, the overlapping or interfltting arrangement ofthe tongues H and I2 through which the fastening nails are also passed.

' elled as indicated at I1. The recess I5 presents a perpendicularsurface I 5a which is joined tothe outer surface of the base 5 by aninclined surface I5b. A portion of the felt covering stripv 1 isdepressed, as indicated at I1c, into contact with the surfaces I5a andI5b of said recess and completely covers the same. I'he lower edge ofthe felt covering strip 1 of each base Vmember 5 terminates flush withthe bevelled edge I1.

With the sections A', B and C' assembled as illustrated in Fig. 2 itwill be noted `that the depressed portion |1c of the felt covering ofeach section, together with the underlying portion of the base 6, isreceived in the recess I6 of the next upper section so that the portionof the felt covering overlying the inclined surface |5b of the recess I5of the lower section is flatly engaged by the bevelled edge I1 of thebase member 5 of the upper section, the portion of the felt coveringoverlying the surface I5a being conned between 'said surface and theopposing surface of the recess IS. The sections A', B' and C are securedin assembled relation and to the wall 5 by means of fastening nailsdriven therethrough as indicated at I 9 so that the overlapping portionsof the sections are firmly pressed together to provide a waterproofjoint.

In the construction illustrated in Fig. 3 the upper edge of each sectionis formed in substantially the same manner as described in connectionwith Fig. 2 except that the depth of the recess I5 is reduced so that itis substantially equal to the thickness of the felt covering strip 1. Inthis modification the lower edge 6d of the base 6 ofr each section iscut square and is spaced above the lower edge of the felt covering 1.The felt covering is thereby projected below the lower edge of the basein the form of a tab 1d which, in the assembled relation of thesections, overlies that portion 1c of the felt covering of the nextlower section which is depressed into contact with the walls of therecess I5. The sections here referred to are secured to the wall 5 bymeans of nails |9a which pass through the felt portions 1c and 1d ofeach section and through the underlying portion of the base 6.

In the construction shown in'Fig. 4 the base of each section is composedof two parts designated 20 and 2|. 'I'he outer part 20 is made of amaterial selected particularly with reference to its insulatingqualities while the inner part 2| is made of a different material havinggreater fireproong qualities. The outer portion 20 may, for example,consist of the materials' usually employed in the manufacture of highinsulating characteristics while the inner portion 2| may be made of thematerials employed in the manufacture of products of high iireproongcharacteristics. As herein shown the two portions of the base aresecured in face to face relation with the upper and lower edges of theportion 20 spaced below the corresponding edges of the portion 2|. Thefelt covering strip 1 entirely covers the outer surface of the portion20 and has its upper edge 1e projected therebeyond and depressed intocontact with the surface of the portion 2| which is exposed above theupper edge of the portion 20. The inner surface of the portion 20 whichprojects beyond the lower edge of the portion 2| is cut or shaped toprovide a recess 22 of a depth approximately equal to the thickness ofthe felt covering strip 1. When the sections are assembled together thedepressed 5 felt portion 1e at the upper edge of each section isreceived in the recess 22 of the next upper section, the opposing upperand lower edges of the base portions 2l of the secions being buttedtogether as illustrated in Fig. 4. In effect, the construction shown inFig. 4 is practically the same as that shown in Fig. 2 except that thebase is made in two portions composed of different materials selected toprovide a. covering product of high insulating and fire resistingqualities. 15
